LPS350 Series
350 Watt AC-DC Power Supplies

The LPS350 series of enclosed AC-DC power supplies comprises four models, providing standard voltages of 5 V, 12 V, 15 V or 24 V. All four models also provide 5 V standby and 12 V fan outputs. They accept a universal input of 85–264 Vac or 120–300 Vdc. Features include single wire current sharing, remote sense and remote inhibit, plus remote power fail and DC power good indication. Enclosed LPS350 power supplies can be specified with end or top mounted fans and can deliver up to 350 watts of output power. Versions without a fan are available for applications which provide an alternative means of cooling.
